Type of employment


Would you like to take part in the development of a new scientific instrument? We are offering a challenging Master Thesis at our department in Almeria, Spain!

We are developing a multispectral infrared imager within international research projects, in order to measure temperature and emissivity maps of solar thermal tower central receivers. The knowledge of the temperature and emissivity are both critical for a solar thermal tower power plant, in order to guarantee an efficient operation of the thermal receiver on the one hand, while monitoring any degradation of the receiver coating on the other hand.

You will be engaged in developing a software routine for the digital image processing of multispectral datacubes, applicable for different test configurations. Raw infrared images have to be processed stepwise, in order to derive temperature and emissivity maps applying ratio thermography.

  • You will develop a software routine in MATLAB (Image Processing Toolbox) for the automatic digital image post-processing of multispectral infrared datacubes.
  • You will evaluate different image correction algorithms in the imaging process, e.g.:
    • Non Uniformity Correction (NUC)
    • High Dynamic Range Imaging (HDRI)
    • Chromatic image registration
    • Atmospheric compensation
    • Radiometric calibration
  • You will suggest improvement measures in the image acquisition process, in order to optimize the measurement accuracy.

Your qualifications:

  • You are a Master or Bachelor student in Engineering, preferably applied Computer Science (/Image Processing / Machine Vision) or Mathematics.
  • You have software skills using Matlab, Python or similar.
  • You like to identify and resolve problems.
  • You are a good team player and able to work independently.
  • You have good knowledge of English and/or German.

Your benefits:

Look forward to a fulfilling job with an employer who appreciates your commitment and supports your personal and professional development. Our unique infrastructure offers you a working environment in which you have unparalleled scope to develop your creative ideas and accomplish your professional objectives. Our human resources policy places great value on a healthy family and work-life-balance as well as equal opportunities for persons of all genders (f/m/x). Individuals with disabilities will be given preferential consideration in the event their qualifications are equivalent to those of other candidates.
